  When an ion generator that generates ions by a discharge phenomenon is used for a long time, dirt substances such as dust contained in the air adhere to the electrodes, and the discharge surface is eventually covered with the dirt substances. If a dirt substance adheres to the discharge surface, corona discharge for generating ions may be hindered, and ion generation efficiency may be reduced. Therefore, it is necessary to clean the electrodes for generating ions with a cleaning tool such as a brush to remove the adhered dirt substances.

  However, since the ion generating element is arranged so that it cannot be easily touched from the outside, it is often difficult to perform maintenance. Therefore, if the structure is such that the ion generator can be removed during cleaning, the number of parts may increase, and if an impact such as dropping is applied to the removed ion generator, damage or failure will occur.

A panel 10 is detachably attached to the housing 1 so as to face the suction port 2. The panel 10 has openings in a lattice shape having a size almost equal to that of the suction port 2. The dust removal filter 2 a is slightly larger than the suction port 2 and the opening of the panel 10, and is sandwiched between the suction port 2 and the panel 10.

  The discharge port 4 is an opening formed on the upper surface of the housing 1. A lid 5 is detachably attached to the housing 1 so as to close the discharge port 4. The lid 5 has a lattice shape. The lid 5 is provided in order to prevent foreign matter from entering the ventilation path 3 from the discharge port 4 and preventing the user from putting hands during operation.

  The ventilation path 3 is integrally provided inside the housing 1 so as to communicate the suction port 2 and the discharge port 4.

  A motor fixing portion 11 is fixed outside the ventilation path 3 inside the housing 1, and a fan motor 9 provided in a blower 7 described later is fixed inside the housing 1.

  The blower 7 is attached to the inside of the housing 1. The blower 7 includes a fan 8 and a fan motor 9. The fan motor 9 is attached to the outside of the ventilation path 3 inside the housing 1 by a motor fixing portion 11, and a motor shaft that rotates the fan 8 protrudes from the inner wall surface of the housing 1 to the ventilation path 3. A fan 8 attached to a motor shaft protruding into the ventilation path 3 faces the suction port 2.

  When the fan motor 9 is driven and the fan 8 rotates, air is sucked from the suction port 2. Dust contained in the sucked air is removed by the dust removal filter 2 a and passes through the ventilation path 3. The air that has passed through the ventilation path 3 is discharged from the discharge port 4 to the outside of the ion generator 100. In addition, the arrow shown in FIG. 1 shows the flow direction of the air discharged | emitted from the discharge port 4 through the ventilation path 3 from the suction inlet 2. FIG.

  The ion generator 12 is attached to the inner wall surface of the housing 1 that forms the ventilation path 3. The position of the ion generator 12 in the ventilation direction is behind the fan 8 and slightly forward of the discharge port 4.

  The ion generator 12 emits ions by corona discharge. FIG. 3 is a plan view of the ion generator 12, and FIG. 4 is a perspective view of the ion generator 12. The ion generator 12 has an outer shell composed of a casing 24 and a case lid 23. The casing 24 has a substantially rectangular parallelepiped shape with one side opened. A case lid 23 is attached to the opening side of the casing 24. The case lid 23 has a plate shape and is provided with two through holes having the same size.

  The casing 24 includes two ion generation units 21 and 22 and a power supply unit (not shown) inside. The ion generator 21 includes a discharge electrode 21a and a dielectric electrode ring 21b, and the ion generator 22 includes a discharge electrode 22a and a dielectric electrode ring 22b.

  The discharge electrode 21a is a needle-like electrode. The dielectric electrode ring 21b is an annular electrode. The discharge electrode 21a is disposed so that its axial center coincides with one through-hole of the case lid 23, and the dielectric electrode ring 21b is disposed in the casing 24 so as to surround the discharge electrode 21a and the through-hole so as to surround the outside of the through-hole. They are arranged with their axes aligned. Similarly, the dielectric electrode ring 22b and the discharge electrode 22a are also arranged so that their axial centers coincide with other through holes. A plane perpendicular to the discharge electrodes 21a and 22a is referred to as an ion generation surface.

Ions are generated by supplying voltage to the discharge electrodes 21a and 22a and the dielectric electrode rings 21b and 22b from a power supply unit (not shown). The ion generator 21 and the ion generator 22 generate ions having different polarities. More specifically, a positive voltage is applied to the ion generation unit 21, and water molecules in the air are electrically decomposed in a plasma region due to discharge to mainly generate hydrogen ions H ⁺ . Water molecules in the air aggregate around the hydrogen ions H ⁺ to form positive cluster ions H ⁺ (H ₂ O) _m . Here, m is an arbitrary natural number.

A negative voltage is applied to the other ion generator 22, and water molecules in the air are electrically decomposed in the plasma region due to discharge, and mainly oxygen ions O ₂ ⁻ are generated. Water molecules in the air aggregate around the oxygen ion O ₂ ⁻ , and negative cluster ions O ₂ ⁻ (H ₂ O) _n are formed. Here, n is 0 or an arbitrary natural number.

  The ion generator 21 and the ion generator 22 may switch the polarity of the generated ions every predetermined time.

  Returning to FIG. 1, the ion generator 12 is rotatably mounted in the ventilation path 3 with a rotation shaft in a direction intersecting the ventilation direction. In FIG. 1, the ion generation surface is parallel to the ventilation direction in the ventilation path 3, and the two through holes of the case lid 23 are arranged in a direction perpendicular to the ventilation direction in the ventilation path 3.

  The ion generator moving means 13 supports a side surface close to the bottom of the casing 24 and attaches the ion generator 12 to the inner wall of the housing 1 so as to be rotatable. The ion generator moving means 13 includes a rotation shaft, a stepping motor, a gear, and an idle gear.

  The rotation shaft protrudes from the outside of the ventilation path 3 to the inside of the ventilation path 3 so as to intersect the ventilation direction, one end is attached to the lower side of the side of the ion generator 12, and the ion generator 12 is rotated around the axis. It is possible to move.

  The gear, the idle gear, and the stepping motor are provided outside the ventilation path 3. The gear transmits the rotational force generated by the stepping motor to the rotation shaft, and the idle gear is provided to decelerate the rotational force generated by the stepping motor. After the idle gear decelerates the rotational force of the stepping motor, it is transmitted to the gear and further to the rotating shaft. As a result, the rotation shaft is rotated to rotate the ion generator 12, and the position of the ion generator 12 is generated from the operation position where the ion generation surface is substantially parallel to the ventilation direction of the ventilation path 3. The cleaning position is changed so that the surface faces the direction of the discharge port 4.

  The illuminating device 15 is attached to the inner wall constituting the ventilation path 3 slightly above the upper discharge port 4 than the position facing the ion generator 12. The lighting device 15 is turned on and off under the control of the controller 30. The illuminating device 15 illuminates the case lid 23 when the ion generator 12 is in the cleaning position. As a result, the operator can easily visually check the contamination of the discharge electrodes 21a and 22a and the dielectric electrode rings 21b and 22b provided on the ion generation surface, and the vicinity of these electrodes and the case lid 23 can be easily cleaned. Become. For example, a white LED may be used as the illumination device 15. By using the white LED, it is possible to improve the visibility when the operator confirms the ion generation surface with low power consumption.

  The lid detection sensor 6 is attached to the inner wall near the discharge port 4 of the housing 1 so as to come into contact with the lid 5 attached to the discharge port 4. The lid detection sensor 6 detects whether or not the lid 5 is attached to the discharge port 4. The lid detection sensor 6 outputs a detection signal to the controller 30.

  The lid detection sensor 6 is, for example, a tactical switch. When the lid 5 is attached to the discharge port 4, the tactical switch is pushed. When the lid 5 is removed from the discharge port 4, the tactical switch is opened. . Thereby, it can be detected that the lid 5 is removed from the discharge port 4.

  The lid locking means 16 projects from the edge of the discharge port 4 outside the discharge port 4 relative to the cover 5 so as to cover the edge of the lid 5, and is attached to the housing 1a so that at least a part thereof can be accommodated. The lid lock means 16 extends over the edge of the lid 5 so that the lid 5 cannot be removed from the outlet 4, and the lid 5 is housed inside the housing 1 and can be removed from the outlet 4. It can be moved to the unlocked position. The position of the lid 5 is controlled by the controller 30.

  The display means 17 displays that the electrode of the ion generator 12 is at the cleaning time. The display unit 17 is, for example, an LED provided on the operation panel, and displays that it is the cleaning time by turning on, blinking, or turning off. For example, it is turned on during the cleaning period and turned off in other cases. The display by the display means 17 is controlled by the controller 30.

  The operation panel 18 receives an instruction input from the operator and outputs the instruction to the controller 30. The operation panel 18 includes, for example, an operation switch that inputs operation start and stop, and a cleaning reset switch that inputs that the accumulated value is reset to 0 when the accumulated operation time is counted.

  The controller 30 illustrated in FIG. 2 is disposed, for example, inside the housing 1. The controller 30 is connected to the lid detection sensor 6, the blower 7, the ion generator 12, the ion generator moving means 13, the illumination device 15, the lid lock means 16, the display means 17, and the operation panel 18.

  The controller 30 includes a control unit 31 and a timing device 32. The control unit 31 controls each unit connected to the controller 30. The control unit 31 interfaces with the lid detection sensor 6, the blower 7, the ion generator 12, the ion generator moving unit 13, the illumination device 15, the lid lock unit 16, the display unit 17, and the operation panel 18. It has a function, communicates with each of these units, outputs a control signal, and receives information signals output from each unit.

  More specifically, the control unit 31 outputs operation start and stop control signals to the blower 7 and the ion generator 12. The control unit 31 outputs a control signal for moving the ion generator 12 to the operation position and the cleaning position to the ion generator moving means 13. The control unit 31 outputs control signals for turning on and off the lighting device 15. The control unit 31 receives a signal indicating whether or not the lid 5 is attached to the discharge port 4 from the lid detection sensor 6. The control unit 31 outputs a control signal that moves to the lock position and the unlock position to the lid lock unit 16.

  The control unit 31 outputs a control signal for displaying to the display means 17 that it is the cleaning time. More specifically, when the display means 17 is an LED, it is turned on when it is the cleaning time, and is turned off when it is not the cleaning time. The control unit 31 receives an instruction signal input by the operator operating the operation panel 18.

  The time measuring device 32 measures the operation time of the ion generator 12. More specifically, the cumulative operation time from when the ion generator 12 is cleaned is counted. The time when the ion generator 12 is cleaned may be, for example, the time when the lid 5 is attached after being removed. The time when the ion generator 12 is cleaned may be when the cleaning reset switch of the operation panel 18 is pressed. The timing device 32 is, for example, a CPU timing function when the controller 30 is configured as a CPU. The timing device 32 is also a clock element connected to the control unit 30 that is a CPU when the controller 30 is configured as a controller board, for example.

  Operations during operation of the ion generator 100 configured as described above and operations when the ion generator 12 is cleaned will be described below.

(Ion generation operation of the ion generator 100 and operation when starting the cleaning of the ion generator 12)
As shown in FIG. 1, when the lid 5 is attached to the discharge port 4, the operator inputs a driving instruction signal by pressing a driving switch from the operation panel 18. When the operation instruction signal is transmitted to the control unit 31, the control unit 31 acquires information indicating that the lid 5 is attached to the discharge port 4 from the signal from the lid detection sensor 6, and the fan motor of the blower 7. 9 is driven to rotate the fan 8 to generate ions from the ion generator 12.

  As the fan 8 rotates, the air from which dust has been removed by the dust removal filter 2 a is taken into the ventilation path 3 from the suction port 2 and moves in the direction of the discharge port 4 through the ventilation path 3. The ion generator 12 has an ion generation surface substantially parallel to the ventilation direction. The ions generated by the ion generator 12 are released above the ion generator 100 from the discharge port 4 together with the air moving in the ventilation path 3.

  When cleaning the electrode of the ion generator 12, the operator presses the operation switch of the operation panel 18 and inputs operation stop. When the operation stop signal is transmitted to the control unit 31, the control unit 31 stops the operation of the ion generator 100. The operator removes the lid 5 after confirming that the operation is stopped. FIG. 5 is a diagram showing the position of the ion generator 12 when the lid 5 is removed. The lid detection sensor 6 detects that the lid 5 has been removed, and outputs a signal to the controller 31 that the lid 5 has been removed. After receiving this signal, the control unit 31 controls the ion generator moving means 13 to rotate the ion generator 12 so that the ion generation surface faces the direction of the discharge port 4 as shown in FIG. Move to. The control unit 31 further turns on the lighting device 15. Thereby, the illuminating device 15 illuminates the vicinity of the case lid 23. With the above operation, the operator can easily clean the vicinity of the case lid 23 including the electrodes.

  When the operator removes the lid 5 while the ion generator 12 is generating ions, the lid detection sensor 6 sends a signal indicating that the lid 5 has been removed during operation to the control unit 31. The controller 31 stops driving the fan motor 9 and generating ions from the ion generator 12. The control unit 31 further controls the ion generator moving means 13 to rotate the ion generator 12, moves the ion generator 12 from the operating position to the cleaning position, and turns on the illumination device 15.

  Since the high voltage is applied when the ion generator 12 generates ions, the removal of the lid 5 and the stop of the operation of generating ions of the ion generator 12 are linked to increase safety. be able to.

(Display control of ion generator cleaning time by timing)
During the ion generation operation of the ion generator 12, the timing device 32 measures the operation time and outputs information related to the operation time to the control unit 31. The control unit 31 acquires information related to the operation time output by the time measuring device 32 and acquires the total operation time from the time when the ion generator 12 is cleaned immediately before. When the cumulative operation time exceeds a predetermined time, the control unit 31 determines that the cleaning time has arrived, and turns on the display unit 17 that is turned off.

  When a display is made on the display means 17 by the above operation, it is a time when the operator is highly likely to have dirt on the electrode of the ion generator 12, and it is a time when it is desirable to clean. Can know.

  Further, when the cleaning time has arrived, the controller 31 stops the operation of the ion generator 12 and the blower 7, controls the ion generator moving means 13, and moves the ion generator 12 to the cleaning position. You may let them. Further, when the lid lock unit 16 is in the locked position, the control unit 31 may control the lid lock unit 16 to move to the unlock position so that the lid 5 can be removed.

  Note that after the cleaning is performed by the operator, the control unit 31 resets the accumulated value of the operating time and starts to newly acquire the accumulated operating time. The reset may be performed by the control unit 31 when the cover 5 is attached after being removed or when an operator presses a switch provided on a panel or the like (not shown).

  In the above embodiment, the controller 30 controls each part based on the detection result signal from the lid detection sensor 6, but the lid detection sensor 6 is configured as a switch so that the controller 30 does not go through. Each unit may start or stop operating.
